I would expect it would show regular metal, every few inches - like modern reinforcing steel, rather than the all over metal throughout the underside of the roof.

Or buy one, they are not expensive and have lots of uses, possibly see if there is a local metal detectorist or club near.
Whilst repairing, it would be a good idea to think of ways to stop further damp issues continuing the corrosion.
I'd also advise shot blasting the underneath, it'll get in better than the wire wheel.
I'd then Seal it using an epoxy resin, this epoxy resin will also act as a barrier for the condensation and hopefully stop any further corrosion

Any advice on a specific product for the epoxy?
Also is a rust converter necessary as well?
Hi Nick,
What was your solution to this in the end? I have a similar problem. An old lean on concrete flat roof garage with some rust in the ceiling. I'm wondering whether if it is salvagable or knock down and start again. You can see in the pics that we got battered in the last storm before christmas. It could be a big project - can't really afford to hire someone to do, so would look to do it DIY.
Advice, much appreciated. Thanks.

My planned solution (not completed yet) is to clean up any lose material on the underside of the roof, treat the rusted metal with an anti-rust product, and then apply an ‘inverted warm roof’ setup on the outside of the slab. Details about this type of roofing solution can be found - Kingspan is especially helpful in this respect.
Your roof problem appears to be on a smaller scale to what I am dealing with. Perhaps worth costing out as best you can the options -from the smallest intervention to the other extreme of knocking it down completely- and making a judgement based on that. Don’t know what your skill level is but it would require significant research and effort to do it all yourself. All depends on your timescale and budget constraints. Hope that helps.
